Rainbow Trail is a great hiking / biking trail outside of the National Park Boundaries with great overlooks and dispersed camping.
There are 5 overlooks as part of the Rainbow Trail: Timp, North Timp, Locust, Fence, and Parissawampitts (say that 3x fast).
There are also 2 nice overlooks just inside of the National Park Boundary: Point Sublime and Swamp Point. Both have nice views and limited dispersed camping.
They are a bit of a drive to get to. But as they say, anything worth doing is worth doing well, and sometimes that means a drive.
